Other objects of the present invention, not

at this time more particularly enumerated,

will be clearly understood fromthefollow-' tion. Y

The said invention consists, primarily, in the -nov'el-c window opening and;v closing mechanism hereinafter setfrth; and,'fi1r ing detailed description jof thel said invert' the'rinore, ,the invention,consistsl in the seif-` eral novel arrangements and 'combinations ofthe various parts of the sameg'as'well as in the details o the construction thereof, all of which will'be fully described inv the'fol'- lowing specilication, and' then embodied in the apjzvendedclaims..1

The invention is clearly illustrated in the accompanying drawing, in which- :The

representationis that 'of an elevation? ofsaid Wmdow opening v'and closing mechanism, a

portion of the inclosing framevv'orklfof the body or door in which it isfmounted being removed to show the same, andthe .mecha-y nism being shdwn operatedto the" Wilp t dow-member.

` 'Referrin v reference c aracter 1 indicates the b'odyof t e Window or door franney provided with the tfipo'site vertical n l ih W .ich is slidabl dis osed the glasswinnow to the 'said dravvingslthe:

grooves or channels'Z dOYY- memberd so t at t e e latter lisvertically movable therein.' Thereference ,character 4 indicates a cro'ssfpi'ece which-formen part Vof thel frame-'Work of saidjlwindovv4 'or' door` framel. Secured Withinthe interior space 5 at the` lower end o'f said'windovv or door-l` frame is a :fixed verticalffstandard 6, the upp er end of which is secured to said crosspiece 4, and thlolwer 'end of'which is secured to the bottom cross-piece7 4of said window or door frames@v Connected vvith the lower end of said .vertical standard 6 area palr of oppositely extending horizontal arms 8, each being provided with a slot or elongatedV nal-pins 12, upon which are journaled grooved rollers 13 which respectively pass through and ride in said slots or elongated openingslff) of said horizontal arms 8.

The reference character 19 indicates' a' spur-gear 22. The lower end of said rack 24 1s secured in a socket-piece 25 from the lower end of which depends a perforated ear or lug 26. Pivotally connected with said ear or lug 26 is the upper end of a connectingflink 27, the lower end of which is pivot ally connected with thepivot-pin 28 by means of which the two llower members 11 of said'lazy-tongs device are joined together. Said vertical standard Gisprovided with a vertical slot 29 through which said pivotpin extends to its connection with said lower end of said connecting-link 27, and in which the same rides during the extending and collapsing movements of said lazy-tongs device. Secured 'upon the `outer end of said shaft 19l is a suitable handle-member for rotating said shaftr and its gear 22.

` Connected with the vertical standard 6 are.' al` pair of oppositely extending bracketarms 4,1,7eaeh .being provided at its outer endwith a perforated ear or lug 42. The said link 27 is rovided with a crossbar 43 rigi 1y secure thereto, the outer ends of which are providedwith erforated ears or lugs 44, intoy which are ooked the lower ends of counter-balancing springs 45, the upper endsof said springs being connected withf screw-threaded adjusting members 46 which pass through the perforated ears or lugs 42 of s'aid bracket arms 41, and are adjustably suspended therefrom by means of the lock-nut devices 47. Since vthe link 27 is interconnected with saidlazy-tongs de-l vice'lO andthe cross-bar 43 with said link 27, itwill be apparent that the tension or pull of said springs 45 by pulling upwardly upon the latter members will tend to extend said lazy-tongs device, and in such manner counter-balance the weight of the window 3.

The carrier-bar l17 of the window 3 is provided with the slotted runways 48, and the upper members 14 of said lazy-tongs de-` vice 10 are provided with rollers 49which ride' in said slotted runways duringv the movements of said lazy-tongs device and operatively connect the latter with the window-member. ff

The manner of operating the novel win- Secured upon the inner` f ment of the lazy-tongs device. v

is thereupon caused to move downward, its

downward movement being in turn transmitted to said connecting-link 27 and thereby to the lower members 11 of said lazytongs device 10, causing the latter to collapse, and thereby carry down in'itsoguide 2 the window-member Sto its fully opened position, or any desired intermediate open position. To raise the window the handle member is rotated in the opposite direction thereby causing a reverse operation of the mechanism and a consequent extension of, the lazy-tongs device 10, which raises up,`r`-

ward the window-member 3.

Of course, it will be apparent 'thatethe comparatively small or-short movement of the rack is multiplied by the action ofthe lazy-tongs device wherebyvthe full distay cey of travel of the window-member is attained,

consequently less than a complete rotation of said handle-member, shaft and pinion or spur-gear will produce the desired move- We are aware that some changes may be made in ythe various arrangements and com-` binatlons` of the several devices `and parts of our present inventionl without departing from the scope of the same as described in the foregoing specification, and as defined in the claims appended ereto. Hence, we

do not limit our invention to the exact arrangements and combmatlons of the various devices and parts as herein seti forth, and as illustrated in the accompanying drawings, nor do we confine ourselves to the exact details of the construction ofthe said parts.

1. A device for opening and closing windows by means of a lazy-tongs device operated by a rack and-pinion, comprising a supporting means fori saidla'zy-tongs device and said rack and pinion, a link inter- 'onnecting said rack with the pivot-pin of the lowerl members of said lazy-tongs device, means afor guiding and anchorin the lower members of said` lazy-tongs device, a

cross-bar connected with said link, and windowLbalancing springs suspended from said `.supporting means andconnected with said cross-bar. l

2. A device for opening'and closing windows by mea-ns of a lazy-tongs device 0peratedsy by a rack and pinion, comprising a supporting means for.' said lazy-tongs device and said rack and pinion, alink interconnecting vsaid rack with the pivotpin of the lower members of said lazy-tongs deict vice, means for gliiding and anchoring the supportingmeans and connected with said cross-har, and meansfor adjusting the tension of said belanc'mg springs.

' testimony, that we claim the invention set 4forth above we'v have hereunto set our hands this eleventh day of March, i914.
